I think you should use the console window instead of the Run window.
You can get a console window by typing 'cmd' or 'command' in the Run
window, depending on your version of Windows.

Well, running it in a console window will save the last
scroll-buffer-full. You can set your scrollback buffer size (on
better versions of Windows) with some Properties dialog --- I can't
There's little bits of python you could do to save the messages to a
file. I think you can say:
sys.stdout = file.open("output", w)
sys.stderr = sys.stdout

python foo.py will run foo.py by compiling it into bytecode (P-code)
and then running the bytecode; if possible, Python will also save the
bytecode in foo.pyc. In the future, python will check to see if
foo.pyc is newer than foo.py, and if so, it will run the bytecode from
the file instead of recompiling foo.py.

I use Unix, and I type 'man python', which won't work on Win98.
Section 2 of the Python Tutorial has some of what you want; more of it
is in section 6.1.

Sounds like an initialization file for the GNU debugger, to set it up
to run your Python command under the debugger. Dunno why Python
recorded this. Mine sure doesn't.

That's a problem for sure. I don't know where to point you now,
because much of the information you seek is scattered in bits and
pieces among the programming documentation.

Glad you're not giving up!

Assembly language hasn't changed *that* much since the 360.
One of the more fun Python projects people are working on is Armin
Rigo's psyco, which is a Python on-the-fly compiler that compiles
Python bytecode into i386 machine code in core and then jumps to it.
Dunno if it sounds like something you'd like to play with after you
